OPERATING PRINCIPLE
The vehicle with a
G9T
engine is fitted with an additional heating system as an option in some countries (Germany,
Nordic countries...). This comprises an engine coolant heater, mainly for starting when cold.
The heater is switched on if the following three conditions are met:
– starting the engine,
– air intake temperature less than
5
˚
C
,
– coolant temperature less than
75
˚
C
.
The heater is usually switched off when the engine is stopped or the coolant temperature reaches
85
˚
C
.
The temperature is measured inside the heater.
The driver does not control operation.
The system is fitted with several safety features (see
page 61-3
).
The heater is connected as the outlet of the thermoplunger unit on the coolant circuit and operates independently of
this. It is fitted outside the left-hand side member in the front bumper.
